Ezekiel Elliott was involved in an altercation with a HUGE celebrity DJ in Vegas early Monday morning -- with the DJ going off about the incident on video after the fact ... and it's intense.
But, sources connected to Zeke tell us ... the Cowboys star is adamant he wasn't the one in the wrong.
Here's what we know for sure ... Zeke and Dak Prescott were partying at Drai's After Hours at The Cromwell Hotel and Casino where DJ Franzen was hanging out.
DJ Franzen is a huge force in hip-hop -- he's tight with guys like Jay-Z, T.
